59.4.6.2 Configuration

The Automatic Bridge mode can be enabled by setting AESB_MR.AAHB.

The IV (Initialization Vector) field of the AESB Initialization Vector register x (AESB_IVRx) can be used to add a nonce in the encryption process in order to bring even more security (ignored if not filled). In this case, any value encrypted with a given nonce can only be decrypted with this nonce. If another nonce is set for the AESB_IVRx.IV, any value encrypted with the previous nonce can no longer be decrypted (see AESB Initialization Vector Register x).

Dual buffer usage (AESB_MR.DUALBUFF=’1’) is recommended for improved performance.
